MACHINE FOR SETTING UP CARTONS, 81b.

SPECIFICATION forming part of Letters Patent No. 767,445, dated August 16, 1904. Application filed December 20, 1902. Serial No. 135,979. (No model.)

To all whom it may concern:

Be it known that I, l/VILLIAM S. SoALEs, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Setting Up Cartons and the Like, of which the following is a specification.

This invention is an improvement on the machine shown in the application of lVilliam H. .Doble, filed February 1, 1902, Serial No. 92,143.

One feature of the invention relates to the mechanism for feeding the carton onto the forming-block.

Another feature of the invention relates to the mechanism for gluing the flaps.

Another feature relates to the mechanism for folding the flaps after they are glued.

Other features of the invention will be more particularly set forth in the specification.

The invention will be fully described by reference to the accompanying drawings, and the several novel features will be particularly pointed out in the claims at the close of the specification.

In the drawings, Figure 1 is a plan of the carton folding and feeding part of the machine embodying the invention, the mechanism being in the position it occupies when ready for a fresh carton to be placed on the feed-block. Fig. 2 is a front elevation of the machine shown in Fig. 1. Fig. 3 is a detail showing the starting and stopping mechanism.

Mounted on shaft 1 is a spider having a plurality of radiating arms 2, preferably four in number, each spider-arm carrying a forming-block 6. The shaft 1 has an intermittent motion, turning at each period of movement through an arc suflicient to bring the blocks 6 in successive rotation into position to receive 5 a new carton and to carry each carton which is already on a block into position for the next stage in the operation. The particular means for giving the intermittent motion to said shaft 1 forms no part of the present invention. 7 0 One form of mechanism for doing this is that shown in the drawings and is briefly described as follows: Mounted on shaft 7 is a spur locking-disk 7, which engages a slotted disk 8 beneath the spider on the shaft 1. Fastened to locking-disk 7 is a spur 9, which carries a pin 10, which is adapted to engage successively the slots 3 in slotted disk 8. By means of this intermittent-motion device the spider is given a movement through an arc of ninety degrees at each period of movement and is held in its position until it is again moved by engagement of pin 10 with another slot in the disk 8.

Mounted on a rod 11 is a block 12, which 5 receives the opened-up carton and presents it to the forming-block. The rod 1.1, on which block12 is mountechhas both an oscillating and a sliding movement, carrying the block with it. The oscillating movement is for the pur- 9O pose of bringing the block 12 into alinement with the forming-block 6, so that the upward sliding movement of block 12 may carry the carton to the forming-block 6 and to draw the block 12 forward again for purpose of receiving a fresh carton after said block 12 has descended. The mechanism for giving the oscillating movement is as follows: heferring to Fig. 5, rod 11 is slidably mounted in a bearing 13, fixed to or integral with a rocking lever28, which is pivoted in bracket 1-1, projecting from table 31, by a pivot 15. A stop 16 on the rod 11 limits the downward movement of the rod by engagement with the bearing 13. The upper end of rocking lever28 has a projection or pin 29, adapted to engage a stop-post 30, rising from the table 31, to prevent the said rocking lever from turning far enough to carry the rod 11 from its receiving position (shown in full lines in Fig'. 5) past the vertical position, (shown in dotted lines,) where it is in alinement with the forming-block. The lower end of rod 11 is connected by a link 17 with one arm of a bell-crank lever 18, which is'fulcrumed at 37 in the forked lower end of rocking lever 28, the other arm of said bellerank lever being pivoted to a connecting-rod 19. The rear end of connecting-rod 19 is pivoted to one arm. of a lever 20, which is fulcrumed on shaft 21, supported in brackets 22, attached to the frame 23. The other end of the lever 20 engages with a cam on the side of disk 26, which is mounted on shaft 27. A spring 33 connects a tail 3 1, which projects rearwardly from the bell-crank lever 18, with a projection 35 on the rocking lever 28. This spring pulls upwardly on the tail 3 1 and tends to hold the bell-crank lever 18 in a position to retain the rod 11 in its lowermost position. The mechanism being in the position shown in Figs. 2 and 5, the form of the cam 25 is such that when the machine is started during the first part of the rotation of said cam, which pushes connecting-rod 19 forward, the rocking lever 28 will be turned on its pivot until the upper arm strikes the stop 30, the spring 33 being stiff enough to prevent bell-crank lever 18 from turning so as to lift the rod 11. As soon as the upper arm of lever 28 strikes stop 30 the lever 28 can rock no farther, and therefore the continued forward movement of connecting-rod 19 by the rotation of the cam 25 compels the bell-crank 18 to turn in a direction to lift its forward arm and through link 17 to lift the rod 11 and stretch spring 33. The form of the cam 25 is such that the rod 11 will be carried up just far enough for the upper end of the block 12, on which the carton 36 is carried, to reach the lower end of the formingblock 6. Mechanism which will be hereinafter described then engages the carton and carries it onto the forming-block, and the continued rotation of the cam 25 retracts connectingrod 19 and causes the descent of rod 11 and block 12 until the stop-pin 16 strikes the top of bearing 13, and then the rocking lever 28 and rod 11 turn so as to move the block 12 forward, as shown in Fig. 5, into position to re ceive another carton. After the lifting-rod and carrying-bloek 12 have risen to their full height, so that the upper end of block 12 is in contact with the lower end of the formingblock 6, other mechanism, which will be described, slides the carton from the carryingblock 12 onto the forming-block 6; but it is important that before the carton is lifted from the carrying-block 12 the flaps at the upper end of the carton be spread, so as to prevent their engagementwith the end of the formingblock. The spreading mechanism shown is as follows: Referring to Figs. 6 and 7, pivoted in a slotted recess 3'7 in each one of the four sides of the carrying-block 12 is afinger 38, which is normally kept from projecting outward by a spring 39. Seated on a spring 10 in a central longitudinal hole 11 in the block is a rod 12, which normally extends slightly above the top of the block 12. Passing through the rod 12 and through a slot 13 is a pin 1 1, the ends of which engage with the tapering inner faces 15 of two opposite fingers 38, and another pin, 16, passing through the rod 11 at right angles to pin 14, engages with the other pair of fingers 38. Slot 13, in which pin 141 moves, is sufliciently large to allow the end of rod L12 to be pushed back into the block. The block 12 is also slotted at right angles to slot 13 to allow movement of the pin 16. Before the block 12 reaches the end of its upward stroke the rod 12 strikes the lower end of the forming-block 6, and the continued ascent of block 12 will press the rod back on its spring-seat. As the rod 12 is pressed back the pins 411 and 16 will ride down on the inclined faces 15 of the fingers 38, turning them on their pivots, so that their upper ends will project outward, as shown in dotted lines in Fig. 7, and spreading the flaps on the upper end of the carton, so that they will not catch when the carton is slipped onto the forming-block 6. The cam 25 is so shaped that the rod 11 and block 12 will have a short dwell and not begin their descent until after the carton is partially slipped onto the formingblock--at least until the flap portion is entered on the formingblock. hen the rod 11 and block 12 descend and the rod 12 is withdrawn from contact with block 6, the spring 10 will push the end of rod 12 out again, and the springs 39 will push in the fingers 38. v

The mechanism for lifting the carton from the carr 'ingblock and sliding it onto the forming-block will now be described, referring especially to Fig. 5. Slidably mounted on a vertical guide 17, rising from the table 31, is a bearing 18, havinga bracket projection 19, to which are attached. angle-arms having forwardly-extending branches 50, and on the outer ends of these branches are hookshaped carton-lifting fingers 51, extending toward each other into the path of movement of the carrier-block 12. In order to permit the fingers 51 to rise and lift the carton from the block 12 onto the forming-block, the block 12 has a vertical groove 52 in its edges. The

lingers 51 should preferably be adjustable to fit carrying-blocks of varying sizes. Pivoted I to a bracket projection 53 on the slidable bearvertical position and not before and will not begin to lift the carton until the upper flaps are spread by the fingers 38. 1V hen the fingers 38 have spread the flaps of the carton, the fingers 51 will engage the lower end of the carton at opposite edges and the bearing 18 will continue to rise until the carton is slipped onto the forming-block as far as the scored lines of the flaps on the lower end. The spider is then given a quarter-turn by the mechanism which will be hereinafter described, and the forn'iing-block 6, with its attached carton, will be carried into position for folding and gluing the flaps. Mechanism is provided which after the block is at rest first turns in the two inside fiaps 58 59, which for convenience may be termed the rear and front flaps, as that is the position they occupy with reference to the direction of rotation of the spider, then applies a coating of glue to the bottoms of these two flaps, Figs. 8 and 13, then folds the right-hand fiap 60, Fig. 9, then glues the under side of that fiap, Fig. 10, then fiolds the fourth or left-hand flap 61, Fig. 11. The finger 62 moves forward and folds the first flap 58. Then the glue-roll 63 moves toward the front and engages and tu ns in the flap 59 and moves across to the front, applying glue to the outside of both flaps 58 59, the finger 62 holding the flap 58 up until it is engaged by the glue-roll. Then the finger 62 withdraws. Then as the glue-roll continues to move toward the front the finger 62 will move again into engagement with fiap 58 and finger 64 will move forward into engagement with flap 59, so as to retain them in position until the right-hand flap-turning roll moves to the left and engages fiap 60 of the carton on the forming-block 6. WV hen flap 60 is turned in enough for it to prevent flaps 58 and 59 from falling, Fig. 9, the fingers 62 and 64: will retreat and roll 65 will continue to advance toward the left far enough to fold flap 60 square up against flaps 58 and 59. Roll 65 will then retreat, the finger 64: moving in to hold flap 60, and the glue-roll will move in the reverse direction-that is, toward the rear of the machineand glue the under side of fiap 60 as it passes under it, the finger 6 1 retreating as soon as the glue-roll has engaged the flap 60. Before the glue-roll has passed off from the flap 60 the finger 62 moves into engagement with flap 60 and holds it up against the inside flaps 58 and 59. The right-hand flap-roll 65 will again move to hold up the flap 60, the finger 62 moving out of the way. WVhile the flaproll 65 is holding up flap 60, the left-hand flap-roll 66 moves forward to fold flap 61, the roll 65 retreating as roll 66 advances. Roll 66 moves across far enough to fold flap 61 squarely and then moves back again. (See Fig. 11.) In order to be sure of turning the side flaps 6O 61 by a square corner, a clamp 67 engages the carton on the left-hand side of the block 6 while the right-hand roll 65 is folding the right-hand flap 60 and a clamp 68 engages the carton on the right-hand side while the left-hand roll 66 is folding the lefthand flap 61.

The mechanism above referred to for folding and gluing the flaps will now be more particularly described.

Flap-folding finger 62 is attached to a horizontally-rocking angle-arm 69, having a bearing 70, by which it is pivoted on a bearingstud 77 on the upper end of post 71, which rises from the table 31. Pivoted to the short arm of angle-arm 69 is a connecting-rod 72, which at its other end engages with and is actuated by a cam 73, mounted on the same shaft 74 which drives the spider-shaft 1. Flapfolding finger 6 1 (referring to Fig. 2) is attached to a horizontally-rocking angle-arm 75, having a bearing 76, by which it is pivoted on bearing stud 77. Projecting from the bearing 76 is a tail 78, to which is pivoted one end of a connecting-rod 79, the other end of said connecting-rod being engaged with and actuated by a cam 80, mounted on shaft 74:. The arm which folds the third fiap 60, which has been referred to as the right-hand flap as the operator faces the machine, is preferably a roller having a series of narrow faces 65 mounted on a shaft 87, which has its bearing in a forked bearing81, (see Fig. 17,) mounted on the upper end of an upright rocking lever 82, the lower end of the said lever 82 being pivoted at 83 to the frame. (See Fig. 1.) Pivoted to said lever 82 is a connectingrod 84, the other end of said connecting-rod being engaged with and actuated by a cam 85, mounted on shaft 86. (See Fig. 1.) The object of the narrow faces is to avoid a wide surface to which the glue would adhere. A spring 88 bears against a tail 89, projecting from the forked bearing 81, and thus holds the roll 65 so as to maintain a yielding pressure on the carton-flaps and permits the necessary rocking movement of the forked bearing 81during the rocking of the upright lever 82.

The mechanism for folding the fourth flap 61 is similar to that for folding flap 60. A roller 66 is mounted in a forked bearing 91, rocking on pivot 92, having its bearings in the upper end of an upright rocking lever 93, the lower end being pivoted at 94to the frame. Pivoted to said lever 93 is a connecting-rod 95, the other end of said connecting-rod being engaged with and actuated by a cam 96, mounted on shaft 86. A spring 98, acting on tail 101 of forked bearing 81, permits yielding movement of said bearing.

Pivoted to the upright lever 82 is a clamplever 97, which has on its upper end an arm 68, projecting toward the forming-block and which is normally held by a spring 99 (broken away in Fig. 2 to save space) in a position overhanging the roller to engage theblock, or rather the carton on the block, when the lever 82 moves toward the block. The overreach of the clamp enables it to engage the carton before the roller on the opposite side folds the flap 61 and serves to hold the block steady, and the spring 99 maintains the pressure while the folding-roller continues to move after the clamp is in engagement. The clamping device on the opposite side is similar to that just described.

Pivoted to the upright lever 93 is a clamplever 100, which has on its upper end an arm 67 and provided with a spring 102.

h'lechanism provided to clamp the carton to the block to prevent it from slipping down out of place during the folding of the flaps. The mechanism shown in the drawings consists of a bent lever 190, fulcrumed at 191 and connected at its lower end with one end of rod 192, which at its other end has a roller engaging with and actuated by a cam 193 on shaft 7s. The end 191 of the lever 190, which presses on the carton, is preferably formed with a rubber shoe.

The flap-gluing mechanism will now be described.

Pivotally mounted in bearings 103 is an upright lever 105, forked at the upper end. Pivoted to the fork-arms 106 of said lever are the rearwardly extending arms 107, between which is the rotary gluing-roll 108, journaled in said arms 107. Projecting from the forkarms 106 are studs 109, which pass through guide-slots in the glue-roll-bearing arms 107 and form a limiting-stop for the arms 107 to limit the upward moven'ient of the arms 107 by the springs 110. The spring 110 presses upward on the arms 107 and normally holds them up. W hen the glue-roll passes under the carton, the pressure of the roll against the flap folded against the lower end of the block causes the spring to yield and to permit the roll to pass entirely across the flap in contact therewith.

Pivoted to the glue-roll lever 105 is a rod 113, connected with and actuated by a rotary cam 111, mounted on shaft 115. Shaft 115 is mounted in bearings 116, supported by the table 31, and is connected by bevel-gear 117 with bevel-gear 118 on the shaft 80, which carries the cams and 96, which control the rollers for folding the third and fourth flaps. The form of the cam 111 is such as to give the proper reciprocating movement to the glue-roll, as already described. The passage of the glue-roll under and in engagement with the flaps serves not only to glue them, but also to fold flap 59. In order to insure passage of the glue-roll without interfering with the side flaps that is, the flaps which have been termed the third and fourth flaps there is carried in front of the glue-roll a guide 119, which passes between the side [laps in advance of the glue-roll in its forward movement. This guide is represented as a bent spring-plate mounted on cross-arm 120, secured to the ends of the glue-roll-bearing arms 107.

The glue-roll 108 may be kept properly supplied with glue in any suitable way. The mechanism shown in the drawings is as follows: Mounted on rotary shaft 121, driven by pulley 122, is a glue-feed roll 123, which extends down into a glue-cup 124k or is supplied constantly with glue applied to its surface in any suitable way. In order to remove the surplus glue from the feed-roll, a scraper 1.26 is secured to a bracket 127 and has arms 128, which extend inward close to the two faces of the feed-roll, and the blade also lies close to the periphery of the roll for some distance in from the edges. In the middle of its edge the scraper is slotted at 129 to permit a band of glue of the proper width to pass through. A. supplementary scraper 130 is adjustably attached to the upper side of scraper 126 and over-reaches the slot 129, so as to regulate the thickness of the film of glue allowed to pass.

Mechanism is provided for rotating the glue-roll108 at the proper times. The mechanism shown is described as follows: Mounted on the glue-roll shaft 195 is a disk 196. Mounted on a slidable rotary shaft 197 is a disk 198, which is adapted to engage with disk 196 when the shaft 197 slides to the right from the position shown in Fig. 1, forming a friction-clutch, and when so engaged the rotary movement of shaft 197 will be imparted to the glue-roll. Mounted on shaft 197 is a spur-gear 199, which engages spur-gear 200 on shaft 201, which is driven by pulley 122. Shaft 197 is splined to spur-gear 199 in such manner as to permit axial movement of the shaft as well as rotary; but the spur-gear has only a rotary movement. The said shaft has a ball-amlsocket connection 203 with a connecting-rod 20%, which at its other end is engaged with and actuated by a cam 205 on shaft 74c to slide the shaft 197 at the proper time to bring the disk 198 into engagement with disk 196 and rotate the glue-roll.

After the flaps have been glued and folded the next movement or quarter-turn of the spider brings the forming-block, with attached carton, around to the third position, where the flaps are pressed while another carton on the block behind is having its flaps glued and folded and while still another is being put onto the forming-block and a completed one is being thrown off.

The presser-block 131 is connected by a togglejoint 132 with one arm of a bell-crank lever 133, fulcrumed at 134 in the standard 135, rising from the table 31. The other arm of lever 133 is engaged and actuated by a rotating cam 136, carried by a rotating shaft 74, which carries the spur locking-disk 7, said shaft being connected by bevel-gear 137 with bevel-gear 138 on shaft 86, which drives the fiapfolding and gluing mechanism so as to work in cooperation. (See Fig. 1.) The cam 136 is so formed as to lift the presser-block 131 and press the folded flaps of the carton up against the lower end of the forming-block and to dwell for a part of the period of rotation, then to descend in time to be out of the way for the next quarter-turn of the spider. The next quarter-turn brings the formingblock, with attached carton, around to the fourth position, where the carton is removed. The removal may be effected by hand or automatically. In the machine shown in the drawings automatic mechanism is provided. Briefly described, it is as follows: Attached to a vertically-slidable block 140 are throw-off fingers 142, which project into the path of the carton on each side far enough to engage the upper ends of the side panels of the carton when the slide-block descends and strip the carton from the forming-block. The block 140 slides on guide-rods 143 to insure a vertical reciprocating movement of the slideblock and throw-off fingers. The mechanism for actuating the throw-off finger block 140 is as follows: A rod 145 is pivoted at one end to said block, the other end of which is pivoted to one end of lever 146, the other end of said lever being fixed to a rocker-shaft 147, mounted in bearings 148. Fixed to rock-shaft 147 is a slotted arm 149, which carries a bearing 150, slidable therein, through which extends a stud 151 from the arm 152, carried by a rockerbearing 153 on shaft 21, said rocker-bearing 153 being the same one to which is fixed lever 55, which, through cam 57, actuates the mechanism for lifting the carton from the carrying-block onto the forming-block, the cams being so formed as to strip the folded carton from the fourth forming-block while the new carton is being placed upon the first formingblock.

Shaft 74, which carries the spur-disk 7, is connected by bevel-gear 141 with bevel-gear 144 on shaft 27. Shaft 27, which actuates the several mechanisms for holding the carton already described, has a spur-gear 154, which meshes with a pinion 155 on the driving-shaft 156. Mechanism is provided by which the shaft 27 shall stop at the end of each revolution, and mechanism is provided also by which it can be started again. Mechanism is also provided by which it can be continued in its movement at the completion of its cycle without stopping. For mechanical advantages it is preferable that the driving-shaft156 should revolve faster than the shaft 27. Therefore it is geared so that the driving-shaft 156 makes three revolutions while the shaft 27 makes one revolution. Shaft 156 is connected by a clutch with driving-pulley 157, which revolves constantly. In order to stop the shaft 156 at the end of the required number of revolutions, which, as stated, is three in the machine shown in the drawings, mechanism is provided whereby the clutch is disengaged at the end of each third revolution. The mechanism shown is described as follows: Carried on the shaft 156 is a disk 158, and carried on the hub of pulley 157 is a shell 159, having in its inner periphery a series of pockets 160. Carried on a shaft 161, which passes through the side of disk 158, is a pawl 162, which is adapted to engage with one of said pockets 160 in the shell 159, and when so engaged the shaft 156 will revolve with the pulley. Fixed to the outer end of pawl-shaft 161 is a dog 163. A spring 164, (see Fig. 4,) one end of which is connected with said dog and the other end of which is connected with a stud 165, which projects from the disk 158,

tends to keep the pawl 162 in engagement with one of said pockets 160. In order to disengage the clutch, mechanism is provided to trip the dogyand therefore disengage the pawl, after the pulley has made three revolutions, and this mechanism will now be described.

A sleeve 166 is slidably mounted on shaft 27, as by a feather, so as to turn therewith, and has a projecting boss 167, which when the sleeve is in its extreme outer position against the collar .208 is in the same plane as the plane of rotation of the dog 163. A spring 180 on the starting-rod 176, (see Fig. 2,) acting through levers and connecting-rods, tends to hold the sleeve 166 against the collar 208. WVhen the sleeve is in such position, the boss 167 is adapted to'intercept the dog 163 at a certain point in one of its revolutions, and the dog will be turned on its pivot, disengaging the pawl 162 from the pocket 160, in which it is engaged, and stoppingthe rotation of shafts 156 and 27. The pawl will remain thus disengaged until the stop-boss 167 is in some way withdrawn from engagement with the dog 163, and then the spring 164 will throw the pawl again into engagement with one of the pockets 160, so as to connect the two members of the clutch and start the driving-shaft.

The mechanism shown for controlling the release of the stop-boss 167 is as follows: Pivoted on a vertical stud 168 is a lever 169, forked at one end, the fork-arms 170 having pins 171, which fit inacircumferential groove 172 around the periphery of the sleeve 166, so as to be adapted to slide the sleeve on the shaft without interfering with the rotation of the foot the shaft. The other end of lever 169 is connected by a rod 173 with one arm of bell-crank lever 171, fulcrumed at 175, the other arm of said lever 174 being pivoted to the lower end of a push-rod 176,which passes loosely through a guideattached to the table 31. If the lever is to be operated by hand, it is preferably provided with a handle 178 for convenience. A spring 180 normally holds the push-lever up in a position such that the sleeve 166 will be in its position for the boss 167 to intercept the dog 163. \Yhen it is desired to start the machine, the push-rod 176 is pressed down, compressingspring 180, and the sleeve 166 will he slid along on the shaft 27, and the stop 167 being released from engagement with the dog 163 the spring 164 will engage the pawl 1 162 with the clutch and start the rotation. In order to hold the sleeve 166 in its retracted position, as is desirable in case the starting-rod 176 is pressed before the completion, a latch 1S1, pivoted at 182, engages a pin 183 on .folded lever 169, when the sleeve is pushed back. Carried on sleeve 166 is a cam 184:, which at a certain point in the rotation of the shaft will trip the latch 181, and the spring 180 will then throw the sleeve 166 out again into position for the step 167 to intercept the dog 163 and again. disengage the clutch. The adjustment is such that the interception will occur at the end of the rotation of shaft 86. As shaft 156 revolves three times while shaft 86 is revolving once, shaft 156 may revolve some distance after the stop is thrown into engaging position before the interception occurs. By the above-described arrangement the operator is not obliged to wait until the completion of a cycle before starting another or to hold the push-rod 176 down until the completion of the cycle, thus leaving the hands free to be picking up and opening another carton ready for slipping onto the feedblocl; 12 as soon as it is in position. If the machine is allowed to complete its cycle and come to a stop before the push-lever 176 is pushed down to release the latch, time will be lost in the operation of the machine. In order to avoid such delay and keep the machine in continuous operation, the operator can push down the rod 176 as soon as she pleases after the cam 18% has tripped the latch 161 and bring the sleeve and stop 167 back out of the path of dog 163, so that it will not trip the pawl 162 or disengage the clutch. The

operator, if expert, will have suflicicnt time to place a carton on the carrier-block after it has come down into position for receiving a. carton while the gluing, folding, pressing, and strippingmechanisms are at work before time for the next quarter-turn, and thus the machine can be made to do continuous work. If the operator is sufficiently expert, the pushrod may be connected with a treadle, (not shown,) and by holding the treadle down with the sleeve 166 will be retained in po sition where the stop will not intercept the dog at all and the necessity of pushing the lever down each time will be avoided. If for i any reason the operator desires to stop the machine at any time, she can release the foot upon the treadle, and the stop will be thrown into intercepting position, as previously described.
